Patent GB-165819-A (GB)
Title: Improvements in or relating to brake apparatus for railway vehicles and the like
IPC: B61H15/00
Filed: 1919-03-05
Abstract: 165,819. Bowles, G. B. March 5, 1919. Compensating for wear.-Wear of brakes is automatically taken up by means of a triangulated system of members g, h, e, arranged in the brake rigging, two of the members g, h, being provided with ratchet-like connections so that when the brakes are operated by imparting angular movement to the third member e, the articulation of the system is altered and slack is taken up. In the arrangement shown in Fig. 1, the brake blocks a are connected by links d to a lever c and floating lever e, the members g, h being pivoted at one end k to the lever c and formed at the other end with ratchet teeth i, j engaging abutments m, n on the lever e. When the brakes are applied, the abutment m advances one tooth on the ratchet i if there is sufficient wear, and when the brakes are released the abutment n advances one tooth on the ratchet j. The member g may be pivoted to the member h intermediate of its length, or it may be pivoted at u on the lever e and formed with ratchet teeth at its other end to engage the pin k, weighted pawls may be used in lieu of the abutments m, n; or springs may be used to keep the ratchets in engagement with the abutments m, n. To prevent the system from operating to take up play caused by heavy loading of the vehicle, the member g may be extended above the axle or the like, so that heavy loading causes the member g to rest on the axle and disengage itself from the abutment m.

Title: Reversible plough
IPC: A01B3/46
Filed: 1948-02-24
Abstract: 645,213. Agricultural ploughs. BOMFORD, D. R., and HOSIER, A. J. Feb. 24, 1948, Nos. 5500 and 11281. [Class 6(i)] A reversible plough, comprising a longitudinally-extending, cranked plough-beam 1, supported by a rear carriage 11 and by either a front carriage, or a front support 6 mounted on a tractor, and having two sets of plough bodies 2, is characterized in that the reversal of the bodies is initiated by the raising of the beam to free the bodies from the ground, under the action of a power-lift, and the reversal is completed by the reaction of the rear carriage in turning at the end of a furrow. As shown, the support 6 comprises a drawplate hinged at 40 and carrying a pair of front pivots 5 and 14 for the beam. An arm 45, projecting from the beam, is yoked to a transverse beam 50 carried by pivoted arms 49 suspended from the power-lift arms 49<SP>1</SP>. Chains 35, 35<SP>1</SP> connect points on the rear carriage 11 with points on the beam spaced from the pivotal axis. In use, the power-lift is utilized to raise the plough beam to a point just short of the dead-centre position at the end of a furrow and the movement of the rear carriage in turning tips the beam over to the opposite side of the dead-centre, so that, on lowering the beam, the opposite set of tools are engaged. In a modification; the plough is provided with its own front wheels arid a separate power-lift comprising a pivoted ram fed with fluid from a pump on the tractor. Depth of ploughing is adjusted by screws on the fore and rear carriage. Means are provided (Figs. 11 and 12, not shown) so that the tractor and plough may be relatively laterally-offset in action while, at the same time, the movement between them is restricted: Specifications 535,635 and 608,642 are referred to:

Filed: 1918-03-28
Abstract: 122,092. A.B.C. Coupler, Ltd., and Mitchell, J. March 28, 1918. Couplings, non- automatic. - In a non - automatic coupling of the kind in which a pin on one vehicle engages a link or shackle in the opposite vehicle, a bar B is pivoted to the upper end of the vertically movable pin A, and is so shaped that, in the raised position of the pin, it falls inwards by gravity and rests with its lower end on the upper surface of the coupler head so as to support the pin in the raised position. Projections C at the lower end of the bar engage a stirrup D on the couple head so as to prevent entire withdrawal of the pin. The shank B<2> of the bar B is curved so that an inward kick is given to it by the stirrup D when it approaches the limit of its upward movement. In a modification, Fig. 4, a separate link F is pivoted to the bar G and serves as a handle instead of the portion B<1> of the bar in the form shown in Fig. 1. Specification 1663/14 is referred to.

Abstract: 990,035. Door latches. W. PUTSCH, L. PUTSCH, U. PUTSCH, and F. W. PUTSCH. Feb. 13, 1962 [Aug. 1, 1961], No. 5549/62. Heading E2A. In a lock mechanism for a car door a latch lever 20 is attached to a spindle 19 supported in a bushing 17 in an aperture 15 of a base-plate 11. To the other end of the spindle 19, see Fig. 1, is attached a ratchet lever 22 bearing teeth 23, 24 which co-operates with an arm 34 of a spring loaded pawl 21 in the closed position. To open the door from the inside, the arm 37 of a lever 35 is rotated so that its arm 39 abuts against an arm 40 of the pawl 21 to disengage the pawl from the teeth 23, 24 of the ratchet 22 to free the latch 20. To open the door from the outside e.g. by a pressbutton, a rotatable and longitudinally slideable release member 41 is provided with a projection 42, which co-operates with an arm 13 of the pawl 21 to disengage the pawl 21 from the ratchet 22. The end 45 of release member 41 is formed with a recess 49 for engagement with pin 50 of a cylinder lock element, so that the pin may be operated to move the member 41 into an operative or inoperative position. The release member 41 may be operated by means of a plate 51 mounted on a spigot 69 which is in engagement with the lever 35. If the lever 35 is rotated in an anti-clockwise direction plate 51 is unmoved, but by rotation in a clockwise direction the plate 51 is moved so that the slot 57 engages a pin 59 of a lever 58 mounted on the shaft 43 of the release member 41 to displace the member 41. A slide member 63 articulated to the pawl pin 29 is formed with a slot 64 which engages a pin 65 on the base-plate 11 and bears a flange 66 which may engage, on slamming the door, with a pin 68 on the crest portion 67 of the member 41, to displace the member 41 into its basic position where it may be used to open the latch.

Abstract: 856,649. Mechanical presses. GOLDING, W. F. Feb. 12, 1959 [Feb. 20, 1958], No. 5594/58. Class 87(2). The upper platen 4 of a press is fixed to the frame uprights 2, 3 which guide the vertical reciprocating motion of the lower platen 5, the under surface of which is a running surface and rests on slide shoes 6. Shafts 7, on which are eccentrics 8, are supported by bearings 10 and rotated by a worm and worm-wheel 12, 11. The shoes 6 are seated on the eccentrics 8. As described, there are two pairs of parallel shafts, each pair supporting three slide shoes through three eccentrics on each shaft. As the shafts rotate the shoes 6 are given a motion of which the vertical component is transferred to the platen 5 while the idle motion of the horizontal component is absorbed by the sliding of the shoes 6 on the surface of the platen 5. Rollers may be interposed between the shoes and the platen. The shoes have shoulders 18 around which fit strips 17 fixed beneath the platen, ensuring positive movement of the platen when the eccentrics move the shoes on the down stroke. For a similar purpose, though some of the bearings 10 are half bearings, some have caps 20, and bearing caps 19 are also provided to prevent unseating of the shoes 6. from the crank pins 8. To maintain synchronism between the angular movements of the eccentrics, the adjacent shafts 7 of the pairs are connected by gear-wheels 21.
